If you are considering acquiring a BRITA filter system or if you are already a BRITA user and you have a question, why not first browse through the frequently asked questions pages - we may have anticipated your questions and the answer is there. For your convience the frequently asked questions page has been divided into several categories.
The BRITA cartridge is not designed to remove fluoride. Some fluoride is naturally present in tap water, whilst some water companies add fluoride to the water. If you are concerned about the presence of fluoride in your tap water, you should check with your water supplier.
The BRITA cartridge is not designed to remove nitrates. Water companies have to comply with the standards set down in the E.C. water quality regulations; this includes a limit on nitrates. If you are concerned about the presence of nitrates in you tap water you should check with your water supplier.
No ... this cannot happen ... the key step in preventing such an occurrence is a process called INNER EXCHANGE. First the contaminants adsorb (stick to the surface of the materials) and then, over the next few hours, these contaminants permanently absorb through INNER EXCHANGE into the interior of the beads thus preventing any release from the surface back into the water.
All materials used in a BRITA Cartridge are non-toxic, top foodgrade quality and are in no way dangerous. We do specify "KEEP OUT OF REACH OF CHILDREN" as a common sense approach ... after all, who wants to eat carbon and beads?
Occasionally you may find small black particles escape from the cartridge. These are fragments of carbon due to possible carbon abrasion during transport. This can also lead to a slight discoloration for the first two fillings (which should not be consumed). This is completely normal and does not affect the performance of the cartridge. The contents of the cartridge are all food grade quality and completely harmless. Thorough soaking, shaking the cartridge well under water and flushing the cartridge (as mentioned in the instructions for use) will encourage loose carbon particles to be released at this stage and help to eliminate further carbon release during use.
The so called chromatography effect - in terms of filtration - is a process in which a filter first removes material from the liquid that is filtered, but re-releases it again into the filtrate after an unspecified period of time. As a result, there can be a higher concentration of the material in the filtered liquid than in the original liquid. Concerning BRITA water filter cartriges, the release of absorbed pollutants such as lead has never been detected in tests carried out in the BRITA laboratory and at well-known independent institutes, such as the NSF (National Sanitation Foundation) in the USA. For these tests, the filter capacity given was partly exceeded by a factor of two or three without any release of the pollutants that had been absorbed.
Treatment Plants add chlorine at P.O.E. (Point of Entry) to remove germs and ensure they do not re-appear while the water travels many miles through the pipes to your tap (P.O.U. ...Point of Use). While the amount of chlorine added is regulated and not considered dangerous, it does impair taste and odour plus there is a definite chance that it can combine with organic compounds to produce chlorinated hydrocarbons that may lead to health related problems. The activated carbon in the filter will reduce the chlorine by up to 99%.
